Ivy Bridge E is in many ways the same old same old we have seen from Intel over the last few launches. Ultimately we can chalk this up to a lack of competition from AMD, so what we get is a good processor that is only slightly better than the previous generation in terms of performance. Being an owner of an Intel 3960X myself I see no reason to upgrade from the previous generation, useless you are really concerned about the 20W difference in power consumption. From our experience most people that can afford a $1000 processor are not concerned about the power bill and with only marginal improvements on the performance front there is no reason to upgrade from Sandy Bridge E at this point.
